Hello!
From Henry, we know that if we solve the generic two fluid equations like this: we will have a numerical problem. So we need to filter out alpha in this equation by Phase Intensive Momentum technology, But what kind of problem?.. Because in OpenFOAM I saw twoPhaseEulerFoam is using Phase Intensive Momentum technology, but compressibleTwoPhaseEulerFoam does not use it. Also by my lots of tests, compressibleTwoPhaseEulerFoam is robuster then twoPhaseEulerFoam. |

OpenFOAM has abandoned the phase-intensive form since OF2.1 or 2.2 (i'm not sure). Regarding its limitations,
